Systems and methods for a secure millimeter-wave marking system for low-altitude weather-resilient uav operations

Abstract

A multi-dimensional fiducial marking system leveraging millimeter-wave (mmWave) technology addresses critical challenges in urban UAV navigation and localization. Unlike traditional visual fiducial markers, the system offers enhanced security through novel data encoding schemes and robust performance in adverse weather conditions. By integrating individual dielectric reflectors with frequency-selective surfaces into modular arrays, the system encodes spatial and identity information for tamper resistance and authentication. The system enables precise UAV navigation and pose estimation using mmWave radar, providing a secure and weather-resilient solution for urban air mobility applications.
